The Lowdown
Alright crew, Rusty here. Let’s break down what’s happening at Jaconé over the next couple of weeks.
Friday the 7th is a slow start. Waves are tiny at 1ft, and the water is a touch warmer than usual at 73°. The swell energy is weak (106) and the wind is a light cross-off, so you can get wet but it’s nothing special. Saturday the 8th stays small, with a bump to 3ft by the afternoon, but a strong east wind at 25 mph messes it up.
Sunday the 9th is the first real show. A proper SSW groundswell hits 7ft with a long 14-second period. The energy jumps to 1613 – that’s serious power. It’s excellent for experienced surfers only; too big for beginners. The morning is clean with a light cross-off, but the afternoon gets onshore and messy. Monday the 10th holds 7ft to 8ft, but the wind is cross-on, making it choppy and marginal.
The standout window is Tuesday the 11th through Saturday the 15th. Tuesday morning dishes up 8ft of S swell, 13-second period, cross-off wind from the ESE at 15 mph, and clean conditions. The energy is pumping at 1792. Wednesday the 12th is similar with 7ft and a gentle offshore from the ENE at 15 mph in the morning. Thursday the 13th drops to 6ft but still has a moderate offshore, making it very good.
But the absolute best is Friday the 14th and Saturday the 15th. Friday morning brings a solid 7ft S swell with a very long 15-second period, offshore NNE wind at 10 mph, and clean conditions. The energy is a massive 2066. Saturday the 15th is the gem: glassy conditions in the morning, with the wind shifting to SSW at just 5 mph. That’s a glass-off, my friends. The swell is 6ft with a 13-second period, and the energy is 1281. With glassy conditions, it’s the best surf of the whole forecast.
The second week fades. Sunday the 16th is still surfable with 4ft to 7ft, but the wind goes cross-shore and the chop builds. Monday the 17th is a washout with strong 30 mph winds. Tuesday the 18th and Wednesday the 19th are blown out by onshore winds and short, weak swell – this is kite-surfing territory, not paddle surfing. Thursday the 20th offers a late-week consolation: a new SSW swell of 5ft to 7ft with a clean offshore in the morning. Friday the 21st and Saturday the 22nd fade back to small, clean waves but nothing to write home about.
So, the call is easy: Saturday the 15th morning is the pick – glassy, solid, and clean. Friday the 14th morning is a close second. If you’re an experienced surfer, those are the sessions to chase.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
